When I received the new Oculus Rift last month, one of the bundled accessories was a wireless Xbox One controller with a wireless USB adapter. Curiously, despite my system being completely up-to-date, the plug-and-play driver installation was never able to succeed correctly. I have seen similar issues pop up occasionally on Facebook and other discussion groups.
The official Microsoft support link on troubleshooting the wireless adapter suggest a wide range of potential solutions, none-of-which helped in my situation. At the end of the first solution that most closely matched my issue ("The adapter didn't auto-install"), Microsoft tells the reader to attempt the uninstall/update process once more and "if this doesn't work, your adapter needs to be replaced." Luckily that isn't really the case and the fix only takes a moment to apply.
